As others observe, it can&rsquo;t be plugged into a conventional &ldquo;breadboard&rdquo; anyway, so what exactly is the point? What CAN you plug this into with those pins?</p>Rcrowley on DEV-09473 - WIZnet W5100 Network Module with Mag Jack - WIZ811MJRcrowleyurn:uuid:b64bd1fd-68b1-29b8-64f3-731b0f9525202014-03-28T15:21:59-06:00<p>They appear to be connection &ldquo;via"s. To connect the copper on the top side to the copper on the bottom side.

The comments here are a few years old and were specific to a board other than the Mega, so I thought I&rsquo;d share an update.</p>
<p>Arduino Mega R3:
J1-1 to D51 (MOSI)
J1-2 to D50 (MISO)
J2-1 to 3.3v
J2-2 to Reset
J2-3 to D52 (SCK)
J2-4 to D10 (SS)
J2-9 to GND</p>
<p>The important point is that the Serial Slave pin assignment for the Mega is D53, but for some reason the IDE/Software is still using D10 per the Uno.</p>magnomp on DEV-09473 - WIZnet W5100 Network Module with Mag Jack - WIZ811MJmagnompurn:uuid:76732555-17de-ae32-0b10-4e5a7a6faa792013-08-30T07:07:41-06:00<p>What&rsquo;s the current consumption for this?

On the WizNet811mj, I get steady green and flashing yellow lights. I&rsquo;ve tried adding my gateway and changing the mac address and ip, but no difference. I&rsquo;m using USB to power the UNO, but added a 12V supply to the power plug, but no difference there either. Here&rsquo;s my connections for reference:</p>
<p>J1-1 (MOSI) to D11,
J1-2 (MISO) to D12,

J2-2 (/RESET) to Reset</p>
<p>So, is there a way to check communication between the UNO and the WIZ?

However, you can find the pinout for this module inside the datasheet linked above.

It seems that the current draw (according to the Wiznet spec sheet) can be 150ma or so while connected to ethernet. I thought I&rsquo;d mention that ahead of time. I don&rsquo;t see that as a problem, but it did make the regulator heat up without a heat sink, enough to get my attention when my finger touched it while unplugging DC power from the clone board.</p>gamerx on DEV-09473 - WIZnet W5100 Network Module with Mag Jack - WIZ811MJgamerxurn:uuid:81c022f7-d019-b458-c3cb-faa180950a042011-10-06T04:46:49-06:00<p>Just wondering, if the LEDs on the light up when the module is powered on without establishing an ethernet connection?</p>Customer #254181 on DEV-09473 - WIZnet W5100 Network Module with Mag Jack - WIZ811MJCustomer #254181urn:uuid:3fdba92f-c2a1-c8e6-1836-267e2345d7802011-10-02T15:18:15-06:00<p>This sounds like the same problem I was having.

I followed the directions of soldering the kit together but when I try to compile any of the examples on TinyClr&rsquo;s site, they fail. There aren&rsquo;t any errors, they just compile then do nothing. They automatically stops debugging. So I wanted to know what drivers from NETDUINO you used. Anything would be helpful.<br/>
If requested I could show you the ethernet shield kit I used but it&rsquo;s not from SparkFun.<br/>
Thanks.</p>npflood on DEV-09473 - WIZnet W5100 Network Module with Mag Jack - WIZ811MJnpfloodurn:uuid:16ad93e2-2641-90ee-15e0-42ceb78cf02c2011-02-14T13:07:45-07:00<p>Bought one of these for use with my Fez Panda to add networking at a lower cost than the full shield. It works great but I thought I&rsquo;d post a few caveats I ran into when working with this just to help people make their decision&hellip;<br/>
First of all, this really is a full blown alternative to the Arduino shield and works well.<br/>
The soldered on headers are actually kind of a pain. You cannot prototype with this on a breadboard as there are two rows of pins on each side and you cannot short them together in the way a breadboard would. This left me with using jumper wires to connect them to my microcontroller. The wires ended up being long and that caused me a couple hours of debugging before I was able to discern that there was no problem with my software, but that the long wires were causing the SPI connection to be faulty.<br/>
I was able (for FEZ owners) to use the NETDUINO driver for the W5100 instead of the binary drivers provided by GHI and turn down the SPI speed. This made my setup work, albeit a bit slower than it probably should.<br/>
I&rsquo;m probably going to end up desoldering the headers as they are in my way, I kind of wish this had come with them in the box but not soldered on.<br/>
Maybe somebody will have a great solution for me on how they connected theirs.<br/>

Is that correct? The only comment in the datasheet about LED&rsquo;s reads, &ldquo;Supports network status indicator LED,&rdquo; but that doesn&rsquo;t mean that it has it built in.</p>nibbler on DEV-09473 - WIZnet W5100 Network Module with Mag Jack - WIZ811MJnibblerurn:uuid:bc091845-1853-2122-d6c5-250a41c59c982010-07-23T20:37:36-06:00<p>I&rsquo;ve been using this in place of the Arduino Ethernet shield without any hassles so far, other than lacking cable management.<br/>
Refer to the breakout schematic and <a href="http://www.arduino.cc/playground/Code/Spi" rel="nofollow" >http://www.arduino.cc/playground/Code/Spi</a> when making connections.<br/>
Also note that the module requires a 3.3v supply. If you&rsquo;re building your own 3.3v supply (say for example if you&rsquo;re using this with a Pro Mini), make sure you check the datasheet for the 3.3v regulator you choose, as they usually REQUIRE some external capacitors.</p>N8B on DEV-09473 - WIZnet W5100 Network Module with Mag Jack - WIZ811MJN8Burn:uuid:e435b89a-a9a0-6233-acae-b448db5bc8672010-07-14T14:24:30-06:00<p>Well, it is the same IC as on the Shield so the lib should work fine.
